NORFOLK — Kevin Corliss said he was 8, fighting learning disabilities, and repeating second grade at the Lewis Elementary School in Foxborough in 1964 when teacher William E. Sheehan  first targeted him for sexual abuse.

Over the next five years, Corliss said in a recent interview, he lived under a dark cloud of control, intimidation, molestation, and rape that stopped only at age 13, when he was big enough to put an end to it. And then, he said, Sheehan was grooming a younger replacement.
